Kev sib xyaw ntawm huab cua compressor roj
Mar 19, 2020
Cua compressor roj feem ntau muaj cov roj hauv paus thiab cov khoom ntxiv. Lub hauv paus roj yog cov khoom tseem ceeb ntawm cov roj lubricating, uas txiav txim siab cov yam ntxwv ntawm cov roj lubricating. Cov additives tuaj yeem tsim thiab txhim kho qhov tsis txaus ntawm cov roj hauv paus kev ua haujlwm, muab qee yam khoom tshiab yog ib feem tseem ceeb ntawm cov roj lubricating.
1. Lubricant puag roj
Lubricating roj hauv paus roj yog muab faib ua cov roj ntxhia hauv cov roj thiab cov roj hluavtaws hluavtaws. Cov roj ntxhia hauv cov roj tau siv dav, nrog ntau tus nqi (kwv yees li 95% lossis ntau dua), tab sis qee qhov kev siv yuav tsum siv cov khoom tsim nrog cov roj hluavtaws hluavtaws, uas tau ua rau kev loj hlob sai ntawm cov roj hluavtaws hluavtaws.
Mineral roj hauv paus roj yog tsim los ntawm cov roj crude. Cov txheej txheem tseem ceeb ntawm lubricating roj hauv paus roj muaj xws li: atmospheric thiab nqus distillation, hnyav deasphalting, hnyav refining, hnyav dewaxing, av nplaum los yog hydrogenation refining. Xyoo 1995, kuv lub teb chaws cov qauv roj nplua nyeem tam sim no tau hloov kho, feem ntau yog cov txheej txheem kev faib tawm tau raug hloov kho, thiab ob hom qauv roj av tshwj xeeb rau qis -condensation thiab tob refining tau ntxiv. Hauv kev tsim cov ntxhia roj nplua nyeem, qhov tseem ceeb tshaj plaws yog xaiv cov roj zoo tshaj plaws.
Cov tshuaj muaj pes tsawg leeg ntawm cov ntxhia hauv paus roj muaj xws li kub kub taw tes, siab molecular hnyav hydrocarbons thiab tsis yog -hydrocarbon sib tov. Nws muaj pes tsawg leeg feem ntau yog alkane (txoj saw ncaj, ceg saw, ntau-txoj saw), cycloalkane (monocyclic, bicyclic, polycyclic), aromatic hydrocarbon (monocyclic aromatic hydrocarbon, polycyclic aromatic hydrocarbon), cycloalkyl aromatic hydrocarbon thiab oxygen{{3}, nitrogen, Sulfur-muaj cov organic tebchaw thiab tsis yog-hydrocarbon tebchaw xws li cov pos hniav, asphaltenes, thiab lwm yam.
2. Cov tshuaj ntxiv
Cov khoom siv ntxiv yog cov ntsiab lus ntawm cov niaj hnub high - qib lubricating roj. Kev xaiv kom raug thiab tsim nyog ntxiv tuaj yeem txhim kho lawv lub cev thiab tshuaj lom neeg, muab cov khoom tshwj xeeb tshiab rau cov roj lubricating, lossis txhim kho qee yam ntawm lawv cov khoom qub kom tau raws li cov kev xav tau siab dua. Raws li qhov yuav tsum tau ua kom zoo thiab kev ua tau zoo ntawm cov roj lubricating, ua tib zoo xaiv cov khoom ntxiv, ua tib zoo sib npaug, thiab kev sib xyaw tsim nyog yog cov yuam sij kom ntseeg tau qhov zoo ntawm cov roj lubricating. Feem ntau siv cov additives yog: viscosity index improver, ncuav point depressant, antioxidant, detergent thiab dispersant, kev sib txhuam reducer, oily agent, siab tus neeg saib xyuas, anti-foaming agent, hlau deactivator, emulsifier, corrosion inhibitor, anti-corrosion agent Rust agent, breaking emulsifier.
